Introduction

This page explains how to get the config files for using the T2 audio device, which allows use of the 3.5mm headphone port, the built in speakers, the built in mic and the headphones' mic.

Audio Configuration Files

These files can be found here, and there are instructions on where to put them in that gist.

If you are using a 2019 16 inch MBP, use this set of files, as that laptop has 6 speakers and needs slightly different config.

If you are using a 2020 13 inch MacBook Air, use this set of files.

Using Pipewire instead of Pulseaudio

You'll need to modify the /lib/udev/rules.d/91-pulseaudio-custom.rules file from the links above.

SUBSYSTEM!="sound", GOTO="pulseaudio_end"
ACTION!="change", GOTO="pulseaudio_end"
KERNEL!="card*", GOTO="pulseaudio_end"

-SUBSYSTEMS=="pci", ATTRS{vendor}=="0x106b", ATTRS{device}=="0x1803", ENV{PULSE_PROFILE_SET}="apple-t2.conf"
+SUBSYSTEMS=="pci", ATTRS{vendor}=="0x106b", ATTRS{device}=="0x1803", ENV{PULSE_PROFILE_SET}="apple-t2.conf", ENV{ACP_PROFILE_SET}="apple-t2.conf"

LABEL="pulseaudio_end"

Note: The updated locations for the files in the links above for Pipewire distributions will be:

  • /usr/share/alsa/cards/AppleT2.conf
  • /usr/share/alsa-card-profile/mixer/profile-sets/apple-t2.conf
  • /usr/lib/udev/rules.d/91-pulseaudio-custom.rules

Issues

  • Some people are unable to get audio input to work. You may have to use a seperate microphone.
  • All of apple's fancy tuning of the speakers is done in macOS, we don't have anything like that at the moment.
